Description
Yattaran serves as a key crew member aboard the Arcadia in this iteration, displaying a more consistently serious and supportive demeanor. Physically, he possesses a large build, above-average height, dark brown hair, a mustache, and distinctive round glasses. His typical attire includes a dark blue bandanna featuring a skull and crossbones, a light blue shirt with a dark blue horizontal stripe, jeans, and leather shoes.

His personality centers on deep loyalty to Captain Harlock and viewing the crew as family. He extends this camaraderie to new recruits like Yama when they demonstrate skill and care for others. However, he reacts with visible disappointment when plans falter or trust is broken, such as Yama's betrayal. Despite initial reluctance following such events, he remains open to reconciliation when presented with evidence of positive change, particularly when urged by trusted crewmates like Kei Yuki.

Yattaran possesses an intimate understanding of the Arcadia's layout, enabling him to guide crew members efficiently during operations and battles. This expertise extends to tactical deployment in combat, where he favors close-quarters engagements using specialized powered armor equipped with a fin and axe. His technical knowledge proves vital during critical missions, like placing vibration bombs, though he prioritizes rescuing crewmates such as Kei during emergencies.

His history within this iteration includes recruiting individuals meeting the crew's criteria, as seen when he facilitates Yama's initial integration after observing his gunnery skills. During a pivotal mission to shield Earth, he initially follows Harlock's strategy but becomes conflicted upon learning its full implications. This reluctance intensifies after Yama's betrayal leads to the crew's arrest. Following Yama's decision to free them upon discovering Earth's true condition, Yattaran remains wary. He is ultimately persuaded to assist after confirming Earth's habitability and through Kei's advocacy. His involvement proves crucial in freeing the Arcadia and broadcasting the Sanction's deception. In the ensuing battle, he fights boarding soldiers until incapacitated by the Jovian Blaster's impact. He later regains consciousness as the Arcadia departs under new leadership.

Across other official media, the character's core traits remain consistent: he serves as Harlock's first mate, combining expertise in ship maintenance and space combat with a passion for model shipbuilding. His design originates from manga artist Kaoru Shintani, Matsumoto's former assistant responsible for constructing reference models. While often providing comic relief through his model obsession and occasional neglect of personal hygiene, he demonstrates dedication and fearlessness during crises. He notably resents being called a pig. His technical acumen includes encyclopedic knowledge of the Arcadia's structure, ranking second only to its creator, Tochiro Oyama. This expertise allows him to manage repairs and upgrades while effectively operating the ship's weapon systems during combat.
